UNITED STATES PATENT JOHN L. KITE, OF PHILADELPHIA, PENNSYLVANIA,ASSIGNOR OF ONE-HALF HIS RIGHT TO PATRICK F. FOY, OF SAME PLACE.

IMPROVEMENTlN STEAM-GENERATORS.

Specification forming part of Letters Patent No. 212,710, dated February25, 1879; application filed July 8, 1878.

To all whom it may concern.-

Be it known that 1, JOHN L. KITE, of the city and county ofPhiladelphia, in the State of Pennsylvania, have invented a new anduseful Improvement in Steam-Generators, of which the following is aspecification:

The object of my invention is a steam-generator adapted to light work,and which is portable, easily managed, and, entirely safe from thepossibility of explosion; and the nature of the invention consists ofmeans for regulating the supply of water to the boiler orsteam'generator in such quantity as will generate a sufficient amount ofsteam for the work to be done, and discharge the excess of water andregulate the pressure in the boiler according to the work to be done.

Figure l of the drawings represents a vertical section through theboiler A, drainagechamber G, water-tank B, force-pump C, andconnecting-pipes. Fig. 2 is a section, showing the governor-rod with itsattachments on an enlarged scale.

Like letters of reference in both figures indicate the same parts.

Ais the boiler or steam-generator, which maybe made in any desirableform; yet I prefer constructing it, as represen ted, with horizontaltubes to, for the passage of the gas or flames. B is the water-tank, andO a force-pump situated within it, for supplying the boiler with waterat its upper side through the pipe D.

t is a drainage-pipe, attached to the bottom of the boiler, andcommunicating with the drainage-chamber G, into which the excess ofwater from the boiler over that which is generated into steam at eachrevolution of the engine (not seen in the drawings) is discharged. Thechamber is provided with a relief-vah'e, H, attached to the lever I,which is operated by the yoke J of a steam-engine governor, Z, thusadmitting of a free play of the governorrod unless the speed is greatlyin excess.

The operation is as follows: The boiler A being empty, the gas or otherfire is started, and a stroke of the pump throws a small quantity ofwater into the boiler. This water (if there is no excess) is instantlyconverted into steam of a density determined by the capacity of theboiler, and the engine, starting, delivers a given quantity of water tothe boiler at each revolution. If steam is made in excess of the amountrequired to run the engine at its proper speed, the governor opens thewaste-valve K, and allows part of the water to flow into the tank B, anda less quantityis delivered to the boiler and a less amount of steamgenerated or no water is thrown into the boiler and no steam generated.If the speed of the engine be much higher than the proper rate, (fromthe sudden throwing off of its work,) the governor lifts the lever I ofthe relief-valve by means of the yoke J, and relieves the pressure, anddischarges any water that may be in the cham' ber G and its pipes intothe tank B. Any water that may not be converted. into steam by the timeit reaches the bottom of the boiler runs at once into the chamber G,where it remains until discharged by the governor, or by excess ofpressure over the weighting of the relief-valve H, or by lifting thelever for that purpose.

This boiler is therefore absolutely safe, there being no water in theboiler at any time in excess of the amount necessary for one revolutionof the engine, and no pressure higher than that reached by therelief-valve can arise. The relief-valve is always cool, and free fromdanger of sticking from expansion, and the valve-faces are washed byevery discharge of water through the chamber G. If the relief-valveshould by any means be prevented from rising when its proper limit isreached, the increase in the speed of the engine will cause the governorto assist in lifting it.

I claim as my invention- 1. The combination of the waste-valve K withthe boiler and governor, for regulating the supply of water to theboiler, substantially as set forth.

2. The combination of the drainage-pipe E, chamber G, and relief-valveII with the boiler, for draining, collecting, and discharging the excessof water from the boiler, substantially as set forth.

3. The combination of the relief-valve H with the governor, foroperating said valve when the pressure is in excess of the amountrequired for maintaining the proper speed of the engine when notperforming its maximum work, substantially as set forth.
